PAPER BOTTLE.

Specification of Letters Patent.

Patented Feb. 15, 191e.

Application led September 17, 19048. Serial No. 453,514.

Be it known that I, CHARLES FRANCIS JENKINS, citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Paper Bottles, of which the following is a speciiieation, reference being had therein to the accompanying drawing, h

The object of this invention is to provide a paper milkbottle or the like, adapted to show at a glance and while the bottle is closed, the quantity of liquid .contained therein, thus giving such bottle an advantage usually possessed by glass bottles alone.

A further object is to accomplish this result by means which will not appreciably increase the cost of the bottles, this being indispensable to commercial success.

lVith these objects in view, the lateral walls of the bottle are made heavy enough to give the necessary rigidity, but certain portions are made thin so that light may be transmitted, and usually the thin parts are treated with parafn, making them less opaque.

In the accompanying drawings, 'Figure is a side 'view of a bottle or receptacle constituting one of various embodiments of the invention. Fig. 2 is a section on ythe line 2 2, Fig. 1. Fig. 3 is a side view ofV a modified bottle, parts being broken away. Fig. 4 is a partial section similar to-Fig. 2, Fig. 5 is a' like section showing another construction ot' such wall.

In Figs. l and 2, the bottle is shown as having its walls made up ofa heavy and stiff central layer A provided with vertically arranged slots a thin lining layer B, and a thin jacket layer C, the thin layers consisting of paper adapted to be rendered nearly transparent by paraflin and both being usually cemented to the intermediate Fig. 3 shows a bottle made up of spirally I being arranged to break joints with the intermediate strip.

Fig. 4 shows a section of vthe lateral wall of a two-ply bottlethe wall consisting of a heavy layer A4 and a thin lining layer B2. Fig. 5 shows in like manner a form in which the wall consists of a paper sheet A5 yprovided at intervals with depressions F, making it thin at these points. It is evident that other modifications may be made, the essential feature being that the wall shall be heavy enough to give stiffness and shall have portions at variousv heights thin enough to secure the desired degreeA of transparency.

What I claim is:

l. A bottle having thick imperforate paper Walls with relatively small portions of the paper made thinner than the main portion 'and adapted to permit the contents to be seen therethrough at diHerent height-s,

said thin portions being integral with adjacent portions of the body wall.` y

2. A bottlevhaving as constituents` of its lateral wall a primary layer of paper and'a secondary layer of pa er cemented throughout to the first, one o said layers being cut away 'exposing the other .at points varying in height, `the portions thus exposed being transparent.

3. A paper bottle having at different heights relatively small paper portions of its lateral wall thinner than the rest and saturated with paraiinfl '4. A paper bottle having as constituents of its lateral wall a heavy opaque paper layer and a light transparent paper layer, the heavy. layerv being cut away to expose 4the light layer atvarious heights.

In testimony whereof I aiix my signature 1n presence of two witnesses.
